Shanghai Haozhuang Instrument Co., Ltd. develops the LNB brand carbon dioxide incubator, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable
The carbon dioxide incubator is widely used in the research and production of medicine, immunology, genetics, microbiology, agricultural science, and pharmacology. It has become one of the most commonly used conventional instruments in the above-mentioned laboratories. It is formed by simulating in the incubator body A growth environment similar to cells / tissues in organisms such as constant pH (pH value: 7.2-7.4), stable temperature (37 ° C), high relative humidity (95%), stable CO2 level (5% ), A device for in vitro culture of cells / tissues.
Users have two basic requirements for the carbon dioxide incubator. One is that the carbon dioxide incubator can provide the most accurate and stable control of temperature, carbon dioxide concentration and humidity, so as to facilitate the progress of its research work; the second is that the carbon dioxide incubator can Effectively prevent microbial contamination in the incubator, and can regularly eliminate pollution to protect research results and prevent sample loss. Therefore, the most important thing for teachers who buy carbon dioxide incubators is their high reliability, prevention and control of pollution, and ease of use.
Two control systems: infrared sensor (IR) or thermal conductivity sensor (TCD) for measurement. Both sensors are accurate, but each has advantages and disadvantages. The working principle of the thermal conductivity sensor to monitor the concentration of CO2 is based on the continuous measurement of the thermal conductivity of the air in the cavity. The low thermal conductivity of the input CO2 gas will cause the thermal conductivity of the air in the cavity to change, which will produce a direct Proportional electrical signal. Infrared sensor (IR) It uses an optical sensor to detect CO2 levels. The IR system includes an infrared emitter and a sensor. When the CO2 in the box absorbs part of the infrared light emitted by the transmitter, the sensor can detect the amount of infrared reduction, and the amount of infrared light absorbed corresponds to the level of CO2 in the box. , So that the concentration of CO2 in the box can be obtained. Because the IR system determines the CO2 concentration in the box through the reduction of infrared rays, and the particulate matter in the box can reflect or partially absorb infrared rays, making the IR system more sensitive to the amount of particulate matter in the box, so the IR sensor is used in the cultivation of HEPA high-efficiency air filters Inside the box is more appropriate.
